GV80
Fuel Admission Valve for Mid-sized
Industrial Engines
Applications
The GV80 is designed for OEM PFI (Ported Fuel Injection)
applications but can also be used as a retrofit PFI or EFC
(Electronic Fuel Control) application.
In the case of retrofit PFI applications, the mechanical fuel
system is disabled/removed and one or more PFI valves is
mounted just before the engine intake on the air manifold. The
GV80 then injects fuel based on electronic control signals directly
into the intake manifold.
An EFC application uses a GV80 valve in addition to the
mechanical fuel system to electronically control injection timing.
Construction
Materials
All parts exposed to the gas are resistant to
corrosion and stress corrosion cracking
Mounting May be mounted in any configuration, however, a
vertical orientation (valve inlet facing upwards) is
preferred.
